The effect of component-resolved diagnosis on specific immunotherapy prescription in children with hay fever.

BACKGROUND: Sensitization to profilins and other cross-reacting molecules might hinder proper specific immunotherapy (SIT) prescription in polysensitized patients with pollen-related allergic rhinitis (AR). In these patients, component-resolved diagnosis (CRD) might modify SIT prescription by improving the identification of the disease-eliciting pollen sources. OBJECTIVES: We sought to measure the effect of CRD on SIT prescription in children with pollen-related AR. METHODS: Children (n = 651) with moderate-to-severe pollen-related AR were recruited between May 2009 and June 2011 in 16 Italian outpatient clinics. Skin prick test (SPT) reactivity to grass, cypress, olive, mugwort, pellitory, and/or Betulaceae pollen was considered clinically relevant if symptoms occurred during the corresponding peak pollen season. IgE sensitization to Phl p 1, Phl p 5, Bet v 1, Cup a 1, Art v 1, Ole e 1, Par j 2, and Phl p 12 (profilin) was measured by using ImmunoCAP. SIT prescription was modeled on SPT responses first and then remodeled considering also CRD according to GA(2)LEN-European Academy of Allergology and Clinical Immunology guidelines and the opinions of 14 pediatric allergists. RESULTS: No IgE to the respective major allergens was detected in significant proportions of patients with supposed clinically relevant sensitization to mugwort (45/65 [69%]), Betulaceae (146/252 [60%]), pellitory (78/257 [30%]), olive (111/390 [28%]), cypress (28/184 [15%]), and grass (56/568 [10%]). IgE to profilins, polcalcins, or both could justify 173 (37%) of 464 of these SPT reactions. After CRD, the SPT-based decision on SIT prescription or composition was changed in 277 (42%) of 651 or 315 (48%) of 651 children according to the European or American approach, respectively, and in 305 (47%) of 651 children according to the opinion of the 14 local pediatric allergists. CONCLUSIONS: In children with pollen-related AR, applying CRD leads to changes in a large proportion of SIT prescriptions as opposed to relying on clinical history and SPT alone. The hypothesis that CRD-guided prescription improves SIT efficacy deserves to be tested.

Respiratory diseases in pediatric triage: a comparison between a general emergency department and a pediatric emergency department.

OBJECTIVE: In this study, the authors have compared data concerning the pediatric triage that is carried out in 2 large emergency departments (EDs) in Rome, one located in a university pediatric clinic with qualified staff and the other one in a general hospital with a high flow of users and pediatric admissions. METHODS: A total of 324 children were selected (162 per hospital) with ages between 0 and 3 years who went to the ED in the period from October to December 2009 for respiratory pathologic findings at the lower respiratory tracts' expense. We took and compared the following data: assignation of the color code, congruity of the color code, and realization of the reevaluation. DISCUSSION: This study reveals several differences between the 2 structures considered with a clear tendency of nurses of the general ED to underestimate color codes, giving undertriage rates in a significant number of cases. Another significantly important difference was found on the detection of children's vital parameters. One last important parameter that emerged from this study was the lack of attention to the reevaluation of the patient after admission in ED. RESULTS: In the light of what we pointed out, it is necessary to implement the educational and informative quality of the triage operators and educators, planning periodical triage training courses to reduce errors. Particular emphasis must be placed on providing pediatric continuing education for nurses practicing in general ED.
